linux-gnu/bin/ld: cannot find -lib

This error message is indicating that the linker (ld) cannot find a library named "-lib". The linker is used to link together object files and libraries to create an executable file.

There could be several reasons why this error is occurring:

1. The library is not installed on the system: If the library is not installed on the system, the linker will not be able to find it. You can check if the library is installed by running the command "ldconfig -p | grep lib". This will show a list of all the libraries installed on the system.

2. The library is not in the linker's search path: The linker searches for libraries in certain directories. If the library is not in one of these directories, the linker will not be able to find it. You can check the linker's search path by running the command "ld --verbose | grep SEARCH_DIR". This will show a list of directories where the linker is searching for libraries.

3. The library is not named correctly: The linker is looking for a library named "-lib". This is not a valid library name. Library names should start with "lib" followed by the name of the library. For example, if the library is named "mylib", the linker should be looking for "libmylib.so" or "libmylib.a".

To fix this error, you will need to determine which of these issues is causing the problem and then take the appropriate action. If the library is not installed, you will need to install it. If the library is not in the linker's search path, you will need to add the directory containing the library to the linker's search path. If the library is not named correctly, you will need to rename it to start with "lib".
